@weiwilliam thanks,,, I reduced the files by doing compression and shuffling. No changes to precision or removal of fields was done I executed a command like so:

nccopy -d 9 -s -u caliop_l2_extcoeff.geovals.20190722_0217.nc4 caliop_l2_extcoeff.geovals.20190722_0217.shuffle.nc4

there was a more modest 15% reduction in the GeoVaLs file but greater than 80% reduction in the observation!

thanks @weiwilliam for contributing the new unit test and files

@rajichidamb , @chengdang or @jeromebarre could any of you have a look at this

I've compressed (and shuffled) the file to reduce their size and was able to do a pretty substantial reduction, but to merge the associated UFO PR4163 we'll need this too
